Negative is VERY good in that case. I took it to mean something totally different - sorry.
In that case, hopefully your girlfriend eats the same kind of diet as you. Her chances of a negative result are greatly improved if she does. There have been cases of reversal of many different diseases through eating a strick Vegan diet. I learned that from the DVD and book. It makes sense too - as I really feel great since I started doing this. RAVE is an acronym. It is even a little more strict than vegan.
No Refined foods
No Animals or animal products

Good thoughts and prayers are coming your way from me...
